To press beaings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0030. For a 3/8" id, use am-0573.

Changes from 2007 FIRST Wheel

More material has been added to each of the spokes, adding significant structural support

More support for the bearing wall has been added

A harder durometer rubber makes up the treads, providing less traction compared to the 2007 wheel

Treads are a slightly darker color of gray

Made in the USA:

Bearings
were not made in the USA. All other components were designed,
manufactured and assembled in the United States of America.
